按下一个按钮时，OnTouchListener会动画所有按钮

Question

所以我在ListView中的自定义适配器上有3个按钮。 每当我按下其中一个按钮时，按钮就会触发动画，每个按钮都有一个OnTouchListener，动画在ACTION_DOWN上按预期工作。但是在ACTION_UP上，所有三个按钮都会生成动画，而不仅仅是我点击过的按钮。我已将Log.i置于监听器内，它似乎正常工作。还有什么可能导致这个？

下面找到动画和按钮监听器的代码：

           //Animation for the buttons
            final ScaleAnimation zoom_in = new ScaleAnimation(1f, 0.9f, 1f, 0.9f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
            final ScaleAnimation zoom_out = new ScaleAnimation(0.9f, 1f, 0.9f, 1f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
            zoom_in.setFillAfter(true);
            zoom_out.setFillAfter(true);
            zoom_in.setInterpolator(new DecelerateInterpolator());
            zoom_out.setInterpolator(new DecelerateInterpolator());
            zoom_in.setDuration(200);
            zoom_out.setDuration(200);

            final Button likeButton = (Button)convertView.findViewById(R.id.graffiti_like_button);
            likeButton.setOnTouchListener(new Button.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    switch (event.getAction()) {
                        case MotionEvent.ACTION_DOWN:
                            // start your first zoom out Animation here
                            likeButton.startAnimation(zoom_in);
                            break;

                        case MotionEvent.ACTION_UP:
                            // start zoom in animation which returns to original state
                            likeButton.startAnimation(zoom_out);
                            break;
                        case MotionEvent.ACTION_CANCEL:
                            // start zoom in animation which returns to original state
                            likeButton.startAnimation(zoom_out);
                            break;
                        default:
                            //v.clearAnimation();
                            break;
                    }
                    return true;
                }
            });
